The **KWSBS-3CC-R** is a specific electronic component, typically categorized as a **Surface Mount (SMT) Push Button Switch** or a tactile micro-switch. These components are widely used in consumer electronics, automotive interfaces, and industrial controls due to their compact footprint and reliability. --- ## 1. Technical Specifications The following table outlines the typical electrical and physical characteristics of this series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile / Momentary Push Button | | **Mounting Type** | Surface Mount Technology (SMT) | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Contact Rating** | 50mA @ 12V DC (Typical) | | **Operating Force** | 160gf to 250gf (Depending on sub-variant) | | **Travel distance** | 0.25mm ± 0.1mm | | **Operating Life** | 100,000 to 500,000 cycles | --- ## 2. Key Features * **Compact Design:** The "SBS" designation often refers to a small body size, making it suitable for high-density PCB layouts. * **Tactile Feedback:** Provides a distinct "click" sensation to the user, confirming that the circuit has been closed. * **Heat Resistance:** Designed to withstand reflow soldering temperatures (often up to 260°C). * **Tape and Reel Packaging:** The "-R" suffix usually indicates that the part is supplied on a reel for automated pick-and-place assembly. --- ## 3. Pinout and Internal Logic As an **SPST-NO** (Normally Open) switch, the internal logic is straightforward: 1. **State 1 (Idle):** The internal contacts are separated; no current flows through the device. 2. **State 2 (Pressed):** The conductive dome collapses, bridging the contacts and completing the circuit. 3. **State 3 (Released):** The spring mechanism (metal dome) returns to its original shape, breaking the circuit. --- ## 4. Common Applications * **Consumer Electronics:** Power buttons on smartphones, volume rockers, or Bluetooth headsets. * **Computing:** Reset buttons on motherboards or peripheral input devices. * **Industrial:** Interface panels for PLC (Programmable Logic Controllers) and handheld testers.
